Pump Start Relay
IVM-OUT 2-Wire Control Devices can
control pump start relays that have a DC
latching input coil.
Connect the red IVM-OUT wire to the red
wire on the 2-Wire path. Then connect
the black IVM-OUT wire to the black wire
on the 2-Wire path.
Connect the red and white IVM-OUT wire
to the DC Latching Relay. Connect the
black and white IVM-OUT wire to the DC
Latching Relay.
Follow your Pump Start Relay wiring
instructions to connect input power and
pump.
For future troubleshooting or modifi-
cations, it is recommended to leave an
additional 3 feet (1 meter) of 2-Wire cable
stored in each valve box location.
NOTICE
Use only WC20 splice kits for all wiring con-
nections to the 2-Wire Path. Improper wiring
can cause serious damage to your controller
or irrigation system and work must be per-
formed by licensed electrician.
WARNING
All electrical connections and wiring runs must
comply with local building codes. Some local
codes require that only a licensed or certified
electrician can install power. Only professional
personnel should install the controller. Check
your local building codes for guidance.
